Guardian
Monthly
Remote code execution in Hashgraph Guardian ≤3.5.0 enables authenticated Standard Registry users to execute arbitrary JavaScript through unsandboxed Function() constructor in Custom Logic policy block worker. Attackers can import Node.js modules to read container files, extract environment credentials (RSA private keys, JWT signing keys, API tokens), and forge authentication tokens for privilege escalation to administrator access. Requires low-privilege authentication (PR:L). No public exploit identified at time of analysis.
A Stored HTML Injection vulnerability was discovered in the Alerted Nodes Dashboard functionality due to improper validation on an input parameter. A malicious authenticated user with the required privileges could edit a node label to inject HTML tags. [CVSS 4.4 MEDIUM]
